How to model and 3D print hose adapters (in Onshape, with templates)

There are two great vacuum hose adapters that are tied into the customizer but I wanted to make some shapes that were even more customizable. Onshape (which is cloud based CAD software) is free to use for public files so I thought that would be the best software to use. I made some templates: 4” m to DW straight reducer https://goo.gl/flzXUD 4” f to DW straight reducer https://goo.gl/kEJYsq 1.875” f to DW straight reducer https://goo.gl/2HKPRN 1.875” f straight coupling https://goo.gl/g93fjr 1.875” m straight coupling https://goo.gl/GgjqWr 1.875” f elbow coupling https://goo.gl/HUqKgb And also made a video showing how to modify the templates and how to model a hose adapter from scratch: https://www.youtube.com/watch?v=b-8ZF1DM4_E If any one needs any more templates or shapes, please let me know and I'll try to keep the list up to date. Have fun!
